Alvin99, I think the analogy with FMG is not appropriate imo.
FMG had massive iron ore resources that were public knowledge at the time plus a huge iron ore boom was just about to start.
SIR does not have massive nickel resources at this point in time but its $500 million market cap, when compared with a successful nickel miner like WSA , is already anticipating substantial nickel resources .... which are yet to be proven.
